As Firefox 38.0.5 was just released, Firefox 39 reached beta stage and Firefox 40 entered the developer channel. Mozilla has Implemented the Google’s download protection from potentially unwanted software (Chrome already has it, check this blog post) in the Firefox developer edition.
Firefox browser with Unwanted Software Protection feature
Till now Firefox browser uses Google’s safe browsing feature to protect users from visiting malware and phishing sites, now it guards you against unwanted software too.
When you visit unwanted software page like this (don’t fear! It’s just a test page) warning will be shown (check the below screenshot)
Reported Unwanted Software Page!
This web page at itisatrap.org has been reported to contain unwanted software and has been blocked based on your security preferences.
Unwanted software pages try to install software that can be deceptive and affect your system in unexpected ways.
You can get out of that page or redirected to Mozilla’s phishing and malware protection documentation page when you click ‘Why was this page blocked?’
What’s new in Firefox 40 Developer Edition
Apart from unwanted Software protection, Mozilla has designed a new style for Add-ons manager based on the In-content Preferences style (check the screenshot below). This release introduces new performance tools. E10s or Project Electrolysis is enabled by default for testing.
